Woods Hole Oceanographic Institution Research Departments (continued):

Scientists in the G&G Department seek knowledge of the structure, composition, and dynamics of the earth’s interior, the origin and evolution of the earth’s crust, controls on ocean and climate change on time scales of decades to 100 million years, and processes of mass and energy transfer at the land-sea interface.

A collection of 24,000 discreet seafloor core sections are kept in storage that, when combined, represent more than 3,800 individual core sites.

Scientific and Technical staff carry out research in a wide variety of disciplines in the marine geosciences including marine geophysics, tectonics, petrology and geochemistry, paleoceanography and coastal and margins geology. The G&G Department hosts a number of state-of-the-art analytical or instrumentation facilities including the National Ocean Sciences Accelerated Mass Spectrometer Facility, the Northeast National Ion Microprobe Facility, the Ice-Ocean Environmental Buoy Program, and part of the Ocean Bottom Seismic Instrumentation Pool.

G&G department members are currently investigation a wide range of problems including sediment biogeochemistry, submarine hydrothermal systems and the origin of mineral deposits on the seafloor, melt generation and flow in the earth’s mantle, crustal magmatic systems, and seafloor volcanic processes. Research conducted by the department staff spans the entire globe.

Ice Ocean Instrumentation Buoys have been continuously monitoring air, ice, and upper ocean data in the Arctic pack-ice since 1992.
